2 Claims.

This invention relates to ties for holding the wings of revolving doors in their normal radial active positions, and has particular reference to an improved locking and anchoring means for associating the opposite ends of a tie or cable with the door Wings.

The present invention refers generally to door wing holding means of the type set forth in United States Letters Patent No. 1,185,313 and constitutes an improvement upon a cable looking and anchoring means set forth in copending application, Serial No. 515,096, filed February 11, 1931, by one of the joint applicants in the present case.

This invention aims to further simplify and improve the cable locking andanchoring means of the types set forth, without sacrificing any of the efficiency of wing holding devices of this character while effecting a substantial economy both in the production and installationof the device upon the door.

As a further object, the present invention accomplishes the elimination of the necessity of bodily adjusting the cable lock mechanism in the door wing by the provision of an adjustable anchorage for the fixed or anchored end of the cable. 1

As a still further object, the invention contemplates an improved detent means for the releasably locked end of the cable or tie.

A still further object of the invention is to so arrange the gripper structure by which the oversized terminal of a cable or tie is gripped, of which structure the foregoing detent means is a part, as to enable the release of the oversized terminal of said cable by an arcuate swing and without having to pull against the normal tension of the cable in order to afford said release.

With the above recited and other objects in view, reference is had to the following description and accompanying drawings, in which there is exhibited one example or embodiment of the invention, while the claims define the actual scope of the same.

In the drawings:

Figure 1 is a general sectional plan view of a revolving door equipped with door wing ties or cables and looking or anchoring devices therefor constructed in accordance with the present invention.

Figure 2 is a fragmentary face view of one face of a door wing equipped with a cable looking mechanism constructed in accordance with the invention.

Serial No. 524,170

Figure 3 is a similar view of the opposite face of a door wing illustrating the adjustable anchoring means for the fixed end of the cable.

Figure 4 is an inner face view of the looking mechanism applied to the door wing.

Figure 5 is a horizontal sectional view taken approximately on the line indicated at 5-5 in Figure 4.

Figure 6 is a similar fragmentary sectional view taken approximately on the line 6 -6 of Figure 4.

Figure 7 is a transverse sectional view taken approximately on the line '77 of Figure '5.

Referring to the drawings by characters of ref erence, the foldably mounted wings or leaves of the revolving door structure are indicated by the reference characters A, the ties, cables or equivalent elements by the reference characters B, said ties or cables being secured at the opposite ends to the adjacent faces of adjacent door wings or leaves in order to hold said wings or leaves in a predetermined radial relation. As is common in revolving doors of either the semi-collapsible or full collapsible panic proof types, the ties or cables B are fixed or anchored at one end and are automatically or manually releasable at the other end.

The cable locking device and anchoring means includes a pair of escutcheon plates for each wing or leaf of the door, and these plates are respectively designated and termed a body plate 10 and a cover plate 11, said plates being of an appropriate size and applied in fiat contact to the opposite surfaces of the wing or leaf of the door at a proper point to cover and conceal an opening or cut-out portion 12 which extends completely through the thickness of the door wing A. The body plate 10 is formed with a pair of vertically spaced, parallel, inwardly directed upper and lower flanges 13 and 14-. of a depth corre-' element 16 is provided with a transverse forvrard- I 1y projecting lower portion 17 having a curved or rounded end 18. The member 16 is further guided in its longitudinal movement by transverse rods 19, with which a lug 20 on the member '16 cooperates to limit the longitudinal movement thereof in opposite directions. Suitable means,

liq

such as a coiled contractile spring 21, normally urges the gripper element 16 to the limit of its movement, where the lug 20 engages one of the transverse rods 19 while said means or spring tensions the gripper element 16 against opposite movement. As illustrated, the spring is interposed between the gripper element 16 and a tension regulator 22 which is disclosed as a nut longitudinally adjustable on a threaded stem 23 to vary the tension of the spring 21. The stem 23 extends through and is carried by an inwardly projecting lug 24 cast or otherwise formed on the inner surface of the body plate 10. A binding nut 25 is also threaded on the stem 23 and is designed to cooperate with the lug 24 to lock the stem against accidental shifting movement and to maintain the adjusted or regulated tension of the spring 21.

The body plate is formed with an opening or slot 26, which slot or opening is of a height or width exceeding the height of a head or terminal piece 27 carried the end of the cable or tie B which is to be releasahly locked to the door wing. A fixed gripper element 28 is secured to the side of the plate 10 and has a rounded edge 29 protruding beyond the outer end wall so or the slot or opening 26. The end 18 and edge 29 cooperate to receive therebetween the reduced neck portion 31 of the head or terminal .*ce eild oi the terminal piece by direct axial he cable or tie except when the movable ripper element 16 is moved away from the fixed element 28 against the tension of the spring21. The height or width of the slot or opening 26 exceeds the height of the end 18 and edge 29 of the movable and fixed gripper elements 16 and 28 and allows for vertical movement of the te m nal piece or head 27 to disengage the same from the lock mechanism and permit of its withdrawa'i through the upper portion of the slot or opening whereby the said end of the cable or tie may be manually engaged betv een or disengaged irom between the end 18 and edge 29, without affecting the movement or" the slidable gripper element 16. The foregoing movement of the terminal piece 27 is defined as being vertical because it is so nearly straight as to make its actual arcuate direction entirely imperceptible. When the terminal piece 2? is s ung up and down, the swinging occurs from the point of anchorage of the tie on the adjacent door portion, the proviubn of the slot form tion particularly avoiding th necessity of pulling against the normal tension of the tie in attempting to releasethe terminal. When the tension of the tie is once arrived at there will ordinarily be no alteration in it, and the en agement and release of the terminal 27 can be eected without restriction.

In order to positively retain the terminal piece or head 2? in place, a detent 32 is mounted for sling movem nt on the inner side of the body platen) directly above the extension 17 and element 28, and said detent is normally urged to an active pos -ion by spring 33. The detent is provided with an exteriorly projecting manipulating button 34, by means of which it may be moved to an inactive position.

The cover plate 11 may be secured in place in any desired manner but, as illustrated, it is directly attached to the bodyplate 10 by means of screws 36 which extend through tubular inwardly projecting bosses 37 formed on the cover plate 11, which screws are threadedly anchored within threaded bores in mating bosses 38 projecting inwardly from the body plate 10.

The cover plate 11 is further provided with an anchoring boss 40 for the anchored or fixed end of the cable, and said boss is preferably provided with the usual keyhole slot arrangement 41 which receives and removably secures therein .by a pin 42,-an interiorly threaded coupling 43.

The interiorly threaded coupling 43 receives a threaded extremity 44 of a tip 45 which is carried by the cable B. This construction permits of longitudinal adjustment of the cable, whereby the head or terminal piece 27 may be properly adjusted to fit the lock mechanism and insure the proper radial positioning of the adjacent door wings, without the necessity of employing means for bodily shifting the locking mechanism in the door wings, as has previously been the accepted practice. In other words, the lock mechanism, including the plates 10 and 11 forming a casing therefor, may be installed on the door wings and the cables applied with their fixed anchored ends adjusted by screwing the tips into the couplings 13 until the proper taut condition of the cables is obtained.

The head or terminal piece of each cable may be manually engaged or disengaged with the locking mechanism by shifting said head or terminal piece vertically to a position between the end 18 and edge 29 or from between the same after the detent 32 has been retracted. With the terminal piece or head 27 emplaced as illustrated in the drawings, it is obvious that an ex- 27 by direct axial-withdrawal due to the camining action of said head against the curved or rounded end 18 of the movable grip or element 16.

What is claimed is:

1. In a revoluble door having foldable wings, ties to brace the wings in right angular relationship, enlarged terminals on the adjacent ends of a pair of the ties meeting at a medial wing, one of said terminals being rigid and the other terminal being part of an adjustable coupling, means on the respective ties with respect to which said coupling is adjustable, and gripper structure mounted on said medial wing by which said enlarged terminals are held, said structure including confronting elements defining an openended passage for the rigid terminal, and including an anchoring boss with which the enlarged terminal of said coupling has a swivel connection. 7

2. in a revoluble door having adjacent ioldable wings, a flexible tie having headed structures at its opposite ends extending between and connecting adjacent wings, one of said headed structures consisting of a threaded terminal permanently fixed to one end of the tie, and a couplin carrying one of the headed structures and having a threaded socket to receive said threaded-ter- 5.

minal for adjustment thereon, an anchoring boss mounted on the door wing, with which the adjustable headed structure has a swivelli'ng connection, the headed structure at the opposite end of the tie being removably connected with an adjacent door wing.
